HAY-"PRESS.

SPECIFICATION forming part of Letters Patent No. 767,040, dated August9, 1904. Application filed July 17, 1903. Serial No. 166,058. (Nomodel.)

To all whom it may concern.-

Be it known that I, NIL OAYOUETTE, a subject of the King of GreatBritain, residing at Amqui, county of Matane, Province of Quebec,Canada, have invented. certain new and useful Improvements inHay-Presses; and I do hereby declare that the following is afull, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to hay-presses such as used for compressing hayinto compact bundles or bales.

The object of the invention is to provide a simple arrangement forelfeeting the purposes mentioned, with a special view to driving theapparatus by means of an ordinary horse-power.

The invention consists in the construction and combination of parts tobe more fully described hereinafter ancl definitely set forth in theclaims.

In the drawings which fully illustrate my invention, Figure 1 is a sideelevation. Fig. 2 is a plan. Fig. 3 is a longitudinal central section.Fig. 4 is an end elevation.

Throughout the drawings and specification the same numerals of referenceindicate like parts.

Referring more particularly to the parts, 1 represents the body of thepress, which, as indicated, is of the usual elongated rectangular form,comprising a suitable frame 2, mounted upon standards or supports 3 and4 in the manner shown. The body 1 comprises a chamher 5, within whichthe hay is compressed, the forward portion 6 of which chamberconstitutes a guide for a plunger or piston '7, adapted to reciprocatetherein. At a suitable point in its upper wall the said body is pro-Vided with a receiver or hopper 8, through which hay may be introducedto the interior of the body for the purpose of compressing the same, itbeing understood that when the plunger is in its withdrawn position thereceiver 8 communicates with the space below the same.

It should be observed that the aforesaid frame 2 comprises fourlongitudinally-disposed stringers 9 and 9, which project beyond theaforesaid standards 1 as extensions 10, the said standards 4 extendingupwardly from the body, as indicated at 11. Upon the upper sides of thestringers 9 there is supported a transverse shaft or axle 12, the samebeing suitably mounted in the bearings 13 and carrying a belt-wheel 14at its extremity, as shown, which belt-wheel is driven by a suitablebelt 15. Near its opposite extremity the said shaft 12 carries rigidly apinion 16, which pinion meshes with a gear-wheel 17, the same beingcarried upon a second transverse shaft 18, the said shaft being disposedtransversely of the body and mounted in bearings 19, which may besimilar to the aforesaid bearings 13. Near its extremity opposite to thegear-wheel 17 the said shaft 18 carries rigidly a pinion 20, whichpinion meshes with a gear-wheel 21, rigidly mounted upon a crank-shaft22. It should. be observed that this crank shaft is rotatably mountedupon the frame. in suitable bearings 23, between which is disposed acrank 24,

which this crank-shaft comprises. This crank includes a crank-pin 25, towhich there is attached the extremity of a pitman or connecting rod 26,which is attached to the plunger 7, as indicated, and affords means foractuating the same, as will be readily understood. From this arrangementit should appear that the rotation of the wheel 14. is transmitted at amuch reduced velocity ratio to the crankshaft, so as to effect areciprocation of the plunger '7 in the manner suggested. 1

Arrangement is made for facilitating the feeding of the hay into thechamber 5 during the operation of the machine. To this end one extremityof the aforesaid crank-shaft 22 is provided with a crank 27, to whichcrank there is attached a link 28, which is disposed substantiallyvertically, the upper extremity of the said link being pivotallyattached at 29 to a walking-beam or feed-arm 30. It should appear thatthis feed-arm 30 is rigidly attached to a cross-bar 31, and thiscross-bar is provided at its extremities with trunnions or gudgeons 32,which are rotatably mounted in the upper extremities of the extensions11- aforesaid. It should also be observed that though the aforesaidcrank 27 is disposed at one side of the machine the said beam 30 isdisposed in an inclined direction in such a manner as to bring itsextremity 33 substantially above the aforesaid receiver or hopper 8, andat this point the arm has attached thereto pivotally, as indicated at34, a depending head 35, the function of which head is to passperiodically into the said receiver in such a manner as to carry downthe hay into the interior ofthe body, as will be readily understood.

It should be observed that the crank 27 aforesaid is disposedsubstantially at right angles to the crank 24, from which arrangement itfollows that when the plunger 7 is in its extreme forward position thehead 35 is then in its extreme elevated position, and when the plungerbegins to withdraw from the position in which it is shown in Fig. 3 thehead 35 begins to descend, and the head will operate to press down anyhay which had been received by the hopper, so as to bring this hay intothe path of the plunger upon the next stroke.

As the plunger 7 is returning from the position in which it is shown inFig. 3 the elastic force of the hay which it has compressed usuallyoperates to transmit an impulsive force to the crank, which has theeffect of giving a sudden impetus to the machinery, which isundesirable. Arrangement is made for meeting this difficulty. For thispurpose one of the stringers 9 is provided at a suitable point with abracket or standard 36, to which there is pivotally mounted at 37 abrake-lever 38, which brake-lever is movably disposed in substantiallythe position shown in Fig. 1, lying behind and adjacent to the aforesaidbeltwheel 14. This lever is offset laterally, as indicated at 39, sothat a surface 40 may be provided which may come into contact with theperiphery of the belt-wheel, as will be readily understood, the parts atthis point constituting a brake-shoe or its equivalent.

To the upper side of the aforesaid crossbar 31 there is attached a rigidarm 41, which is disposed in an inclined direction, as shown, so thatits extremity 42 lies substantially above the extremity 43 of theaforesaid brake-lever 38, the said extremities 42 and 43 being connectedby acable, such as the chain 44. (Shown upon the drawings.) Thearrangement of the parts is such that when the beam 30 occupiessubstantiallythe position in which it is shown in Fig. 1 the lever 38will be maintained in an elevated position, so that the surface 40 ismaintained out of contact with the periphery of the belt-wheel. When,however, the mechanism has moved so that the beam 30 occupiessubstantially the position 30 in which it is indicated in the dottedoutline, it permits the brakelever 38 to descend, as will be readilyunderstood, so that the surface 40 will.rest upon the periphery of thewheel 14. In this manner at such times a braking force is impressed uponthe mechanism, and it should be observed that the times at which thisbraking force will be applied are identical with the instants atwhichthe return movement of the plunger begins, and it will be rememberedthat just at this time the elastic force of the hay is transmitting animpulsive force to the plunger. From this arrangement the application ofthe brake at this time operates to absorb the force being transmitted bythe hay, so that the resultant effect upon the mechanism issubstantially the same as if the hay had exerted no force upon it. Inother words, the application of the brake just at the proper momentcompensates for the elastic force of the hay and prevents an undesirableimpulse being given to the mechanism, which impulse is especiallyundesirable where the mechanism is driven by means of a belt in a mannersuch as that illustrated, it being understood that a sudden force actingthrough a belt would have a tendency to break the belt or throw it offits pulleys, and even if this catastrophe did not occur the jerk givento the machinery would be transmitted to the horse-power which wasdriving the press and be felt by the horses while at work. This is alsoundesirable.

While I have shown in the accompanying drawings the preferredform of myinvention, it will be understood that I do not limit myself to theprecise form shown, for many of the details may be changed in form orposition without affecting the operativeness or utility of my invention,and I therefore reserve the right to make all such modifications as areincluded with the scope of the following claims or of mechanicalequivalents to the structures set forth.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a hay-press, in combination, a chamber in which the hay may becompressed, a plunger, a wheel, mechanism between said wheel and saidplunger whereby said wheel rotates when said plunger reciprocates, alever constituting a brake which may be applied to said wheel, afeed-arm, automatic means for actuating said feed-arm, and a connectionbetween said feed-arm and said lever, whereby the application of saidbrake may be controlled.

2. In a hay-press, in combination, a compression-chamber, a plunger,means for advancing and returning said plunger within said chamber, awheel adapted to rotate when said plunger moves, said chamber having ahopper adapted to receive hay, a feed-arm cooperating With said hopper,a brake normally impelled by gravity to rest against said wheel, andmeans connecting said brake with said feed-arm for controlling the same.

3. In a hay-press, in combination. a compression-ehamber, a hopperadapted to receive hay, a feed-arm adapted to cooperate with saidhopper, means for rocking said feedarm upon a horizontal axis, aplnnger,a wheel, means for reciprocating said plunger by driving said wheel, abrake impelled by gravity I toward said wheel, and a connection betweensaid brake and said feed-arm.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
